To all 10 item it may concern Be it known that ALFRED ARTHUR QUICK,subject of the K-ing'of Great Britain, and a resident of Ben Arthur, 7Penders Street 5 Thornbury, Melbourne, in, the State of Victoria,Commonwealth of Australia, has invented certa-innew and usefulImprovements in a Device for Haulage or Straining'Pnrposes, of which thefollowing is a specification.

This invention relates to improvements in hauling or straining devicesand refers especially to devices of that class in which comparativelylong, lengths of rope or like flexible members may be operateduponwithout having to provide a winding drum of su'ilicient capacity tovaccommodate the whole length of rope hauled. I

Ordinarily, the hauling or straining rope is either wound around thedrum of a'winch which is sufficiently large to accommodate the same oras in the case of u. warping drum the rope is passed around the drum ofthe winch for several turns and then led ofi the same. In the lattercase the load is maintained by means of the frictional contact betweenthe rope and the said drum and for the purposeof causingthe rope tofrictionally grip the drum it is necessary to maintain a tension uponthe rope after it has been led off therefrom.. This tension is usuallycaused by pulling on the rope by hand or by the use of counter weightsor the like, such means limiting the load holding capacity of thefriction drum owing, to the fact that the said tension has no fixedrelationship to the load.

Moreover it has been proposed to pass a rope to and give it one or moreturns around the drum of awincli; the end. of the rope passing off fromthe opposite side of: the drum being looped around a pulley and thensecured to the frame or other part of the winch, whereby when the drumis rotated to move along the rope away from the pulley the loop will-Ibe lengthened and a strain applied to that part of the rope leading tothe drum.v

I am also aware that it has been proposed to employ pulleys or blocks incombination with the device above described, to increase the purchase ofhauling strain. 'The disadvantage of this form of hauling device is thatit will not work satisfactorily under Application for very heavy loadsas the bite and. side creep on the rope incident to the movement set upas it pays on andpays. off the drum causes excessive wear and therebyrenders the effective life of therope of very short duration.

The object of this. inventioncis to provide a hauling and strainingdevice in which the advantages of lightness, of construction as obtainswith a warping drum or the like is applied to and relatively the same.purposes effected. as is achieved with, a winding drum. v v

I accomplish this object byv providing a novel combination of knowndevices consisting ofJa rotatable winch, a rope and one or moreblocksarranged, and operating in such a manner that as the load is applied tothe rope leading on to the winch a proportional tension is automaticallyapplied to that part of the said rope as it. pays off therefrom and thistension increases or de' creases proportionately with any increase ordecrease inthe load, or strain on the said rope to insure the said ropehaving an effective frictional contact with the said winch.

The invention consists more particularly in, providing a. length of.rope one end of which is secured to and passes from a snatch block toand around a second snatch block to and around. a winch, through thefirst snatch block and back to the frame of the winch or to ananchorage. The frame of the winch is connected to an anchorage and thesecond snatch blockis connected. to a. hauling rope or the position ofthe said" anchorage and hauling ropes may be reversed.

Ina hauling or straining device constructed in accordance with thisinvention the rope does not. take one complete turn around the winch orany of the blocks or pulleys as it pays on or off the same and inconsequence all bite and side creep is eliminatedv and the rope willhave a longer life.

For the purpose of convenience in the description of this invention ashereinafter set out certain terms are employedwhich it, will beunderstood are intended to be read as embracing their equivalents.

In. this specification The term rope will include any other suitableflexible member such as a chain, cable, belt or the like, andvice-versa.

The term winch will include and rotatable drum, barrel, or thelike, andviceversa.

The term block will include a snatchblock, pulley, sheave, bollard orany other device around which a rope is adapted to pass freely and theterm may even include the load itself when it is of a cylindrical formsuch as a log or barrel, and vice-versa.

In the operation of a hauling device con structed according to thisinvention the position of the load and the anchorage may be transposedand it will be clear that 1n the following description where 1t isstated that one member or part of a member is connected to a load andthe other member or part of a member is connected to an anchorage thesame effect may be obtained by transposingthe said load and anchorageand that the said terms are therefore transposable.

I will now describe with the aid of the accompanying drawings severaldifferent constructions embodying the present invention, .but it will beunderstood that I do not wish to confine myself to the preciseconstructions and arrangement of parts described and shown as these aregiven by way of example only. V

In these draw1ngs;- Figure 1 is a view in side elevation of theinvention. i

Figure 2 is a view in perspective of one arrangement of the parts of theinvention adapted particularly for effecting hauling operations. 7

Figs. 3 and 4 are edge and side views, respectively, of a modificationof the invention.

Fig. 5' is a view in perspective of a winch designed for use with theinvention.

Figs. 6 and 7 are views in perspective illustrating different forms ofwinding drums adapted for use.w1th the invention and hereinafter arefully described.

Fig. 8 is a perspective view of the arrangement shown in Fig. 2 with thewinch shown in Fig. 5 applied.

eferring to Fig. 1 of the drawings, the reference letter 79 designates ablock which is attached, as by a rope q, to the load L and this blockwill hereinafter be referred to as the first block. The operating winchwhich in this instance may comprise a pulley 'r rotatably mounted in aframe is secured to an anchorage A by means of a rope g". A sec ondblock .9 is attached to one end of the operating rope a and the oppositeend of'the rope is reeved through the first block 2), then led on toandcaused to take a half turn on the operating winch. The rope is led fromthe pulley r and reeved .through the second block and its end isattached to the frame t of the winch or any other fixed object.

In Fig. 2 of the drawings there is shown of the rope paying on,

the load rope g which may be connected to a heavy object to be moved.

The frame it of the winch in this instance is shown connected by alooped rope u to anchor stakes a driven in the ground but it will beobvious that any other form of anchorage may be used. The end of therope a is fastened to a third stake a in such a way that it can beeasily loosened and again fastened when it is desired to adjust the ropeor to reset the device if it is desired to take a second pull on theobject to be moved. The winch is operated by a lever cl and a pawl e andratchet e are employed to hold the pulley r in a position to retain anystrain applied to the rope.

In operation the second block 8 is placed. near the pulley 'r' and thesaid pulley is operated in the direction of the arrow to cause thesecond block to be drawn toward the first block 79. The strain on thatend of the rope 0. attached to the frame of the winch or to the anchorstake a is equal to half the strain on the other end of the said ropeand as the whole length of the rope is under tension the. frictionalcontact between it and the pulley 1? causes the load to be moved whenthe said drum is operated.

When the block a is near the winch the rope between the winch and theblock p is double, and when the device has been operated to, draw theblock 8 away from the winch and near to the block 2; the rope is trebledthereby resulting in a reduction of the distance between the winch andthe said block 2) by approximately one third without in any way sortening the rope.

The difference in the tension on that part and on that part paying oftthe winch remains proportionately the same no matter how much thehaulage strain is increased or decreased within work ing limits.

Either or both of the blocks 8 and 79 may be designed so as to beoperated in conjunction with or in lieu of the winch to efi'ect theoperation of the device.

A further adaption of the device is shown in Figs. 3 and 4c of thedrawings and in these views a double block is used provided with pulleysp and p. In the arrangement of the parts shown in these views. an end ofthe rope a passes from the second block 8 to and is taken around thewinch 7*, up to and over the pulley 3), down to and around pulley 8, uptoand around the pulley p and then fastenedto the load L. This form ofthe invention operates precisely as that above described with thedifference that both the double block and the winch 1' are. secured toseparate anchorage means and do not move toward each other when a strainis applied to the rope and the pulley ofthe block 8 does not rotate. Theoperation of the winch'rcauses the second block 8 to be drawn away fromthe double block and the load is moved upward.

From the foregoing description of the invention it will be appreciatedthat when the arrangements shown in Figs. 1 and 2 of the drawings are inoperation, the strain on those parts of the rope paying off the blocks 8and p is slightly less than the strain on those parts of the rope payingon to the said blocks'and the differences in the strain at these pointsare caused by the friction set up in the moving parts of the saidblocks. V hen the devices are not in operation the differences in thestrains on the parts of the rope are equalized by the blocks auto--matically adjusting themselves to balance the said strains.

When the mechanical efficiency of the device is considerably reduced byfriction of the moving parts or the co-efficient of friction between thesurfaces of the drum and the rope is not sufficient for the purpose, therope will. not grip the drum with sufficient force to carry the straindue to the load.

In order to increase the frictional contact of the rope upont-he drum ofthe operating winch, I may form rope grooves with inclined sides uponthe said drum and to provide an additional gripping means for increasingthe friction or grip I may employ a shoe or the like and arrange it topress upon the rope passing around the drum.

The peripheries of the drums can be provided with a number of flatsurfaces which. also will help to prevent the rope slipping therearoundwhen the device is in opera-- tion.

In Fig. 8 there is combined the arrange-' ment shown in Fig. 2 and thewinch shown in Fig. 5. In this instance the winch generally designated Ais substituted for the.

winch 9'- and the ropes: A, L, a, g and u are arranged the same as inFig. 2- of the drawings.

In Fig. 5 of the drawings the winch is shown operated by a lever e whichis carried by links w pivoted to the frame and this lever is formed witha cranked or bent portion m arranged to bear on the rope passing aroundthe pulley 1 when the said lever is operated. The pressure of the leveron the rope Prevents the rope slipping should there be any tendency forit to do so due to the blocks not moving freely and resulting in adecrease in the strain on that part of the rope paying off therefrom.One of the links w is fitted with a pawl w for enga ing the ratchet e onthe drum of the winch and a retaining pawl e is fitted to the frame ofti c said winch for preventing any backward movement.

In Fig. 6 is shown a winch pulley i having a tapered rope groove formedtherein anchorage or load, or the terms strain or tension. are used itwill be understood that they may be transposed or substituted one forthe other.
